# Step 3: Scaffold Framework

## STEP GOAL

Generate the test directory structure, configuration files, fixtures, factories, helpers, and sample tests using deterministic mode selection with runtime fallback.

## MANDATORY EXECUTION RULES

- 📖 Read the entire step file before acting
- ✅ Speak in `{communication_language}`
- ✅ Apply knowledge base patterns where required
- ✅ Resolve execution mode from explicit user request first, then config
- ✅ Apply fallback rules deterministically when requested mode is unsupported

---

## EXECUTION PROTOCOLS:

- 🎯 Follow the MANDATORY SEQUENCE exactly
- 💾 Record outputs before proceeding
- 📖 Load the next step only when instructed

## CONTEXT BOUNDARIES:

- Available context: config, loaded artifacts, and knowledge fragments
- Focus: this step's goal only
- Limits: do not execute future steps
- Dependencies: prior steps' outputs (if any)

## MANDATORY SEQUENCE

**CRITICAL:** Follow this sequence exactly. Do not skip, reorder, or improvise.

## 0. Resolve Execution Mode (User Override First)

```javascript
const parseBooleanFlag = (value, defaultValue = true) => {
  if (typeof value === 'string') {
    const normalized = value.trim().toLowerCase();
    if (['false', '0', 'off', 'no'].includes(normalized)) return false;
    if (['true', '1', 'on', 'yes'].includes(normalized)) return true;
  }
  if (value === undefined || value === null) return defaultValue;
  return Boolean(value);
};

const orchestrationContext = {
  config: {
    execution_mode: config.tea_execution_mode || 'auto', // "auto" | "subagent" | "agent-team" | "sequential"
    capability_probe: parseBooleanFlag(config.tea_capability_probe, true), // supports booleans and "false"/"true" strings
  },
  timestamp: new Date().toISOString().replace(/[:.]/g, '-'),
};

const normalizeUserExecutionMode = (mode) => {
  if (typeof mode !== 'string') return null;
  const normalized = mode.trim().toLowerCase().replace(/[-_]/g, ' ').replace(/\s+/g, ' ');

  if (normalized === 'auto') return 'auto';
  if (normalized === 'sequential') return 'sequential';
  if (normalized === 'subagent' || normalized === 'sub agent' || normalized === 'subagents' || normalized === 'sub agents') {
    return 'subagent';
  }
  if (normalized === 'agent team' || normalized === 'agent teams' || normalized === 'agentteam') {
    return 'agent-team';
  }

  return null;
};

const normalizeConfigExecutionMode = (mode) => {
  if (mode === 'subagent') return 'subagent';
  if (mode === 'auto' || mode === 'sequential' || mode === 'subagent' || mode === 'agent-team') {
    return mode;
  }
  return null;
};

// Explicit user instruction in the active run takes priority over config.
const explicitModeFromUser = normalizeUserExecutionMode(runtime.getExplicitExecutionModeHint?.() || null);

const requestedMode = explicitModeFromUser || normalizeConfigExecutionMode(orchestrationContext.config.execution_mode) || 'auto';
const probeEnabled = orchestrationContext.config.capability_probe;

const supports = { subagent: false, agentTeam: false };
if (probeEnabled) {
  supports.subagent = runtime.canLaunchSubagents?.() === true;
  supports.agentTeam = runtime.canLaunchAgentTeams?.() === true;
}

let resolvedMode = requestedMode;
if (requestedMode === 'auto') {
  if (supports.agentTeam) resolvedMode = 'agent-team';
  else if (supports.subagent) resolvedMode = 'subagent';
  else resolvedMode = 'sequential';
} else if (probeEnabled && requestedMode === 'agent-team' && !supports.agentTeam) {
  resolvedMode = supports.subagent ? 'subagent' : 'sequential';
} else if (probeEnabled && requestedMode === 'subagent' && !supports.subagent) {
  resolvedMode = 'sequential';
}
```

Resolution precedence:

1. Explicit user request in this run (`agent team` => `agent-team`; `subagent` => `subagent`; `sequential`; `auto`)
2. `tea_execution_mode` from config
3. Runtime capability fallback (when probing enabled)

## 1. Create Directory Structure

Use `{detected_stack}` from Step 1 to determine directory layout.

**If {detected_stack} is `frontend` or `fullstack`:**

- `{test_dir}/e2e/`
- `{test_dir}/support/fixtures/`
- `{test_dir}/support/helpers/`
- `{test_dir}/support/page-objects/` (optional)

**If {detected_stack} is `backend` or `fullstack`:**

Create the idiomatic test directory for the detected language:

- **Python (pytest)**: `tests/` with `conftest.py`, `tests/unit/`, `tests/integration/`, `tests/api/`
- **Java/Kotlin (JUnit)**: `src/test/java/` mirroring `src/main/java/` package structure, with `unit/`, `integration/`, `api/` sub-packages
- **Go**: `*_test.go` files alongside source files (Go convention), plus `testdata/` for fixtures
- **C#/.NET (xUnit)**: `tests/` project with `Unit/`, `Integration/`, `Api/` directories
- **Ruby (RSpec)**: `spec/` with `spec/unit/`, `spec/integration/`, `spec/api/`, `spec/support/`
- **Rust**: `tests/` for integration tests, inline `#[cfg(test)]` modules for unit tests

**If `config.tea_use_pactjs_utils` is enabled and runtime is Node.js/TypeScript** (i.e., `{detected_stack}` is `frontend` or `fullstack`, or `{detected_stack}` is `backend` with Node.js/TypeScript runtime):

Create Node.js/TypeScript contract testing directory structure per `pact-consumer-framework-setup.md`:

- `tests/contract/consumer/` — consumer contract test files (`.pacttest.ts` extension)
- `tests/contract/support/` — pact config, provider state factories, consumer helpers shim
- `scripts/` — shell scripts (`env-setup.sh`, `publish-pact.sh`, `can-i-deploy.sh`, `record-deployment.sh`)
- `.github/actions/detect-breaking-change/` — PR checkbox-driven breaking change detection
- `.github/workflows/contract-test-consumer.yml` — consumer CDC CI workflow

---

## 2. Generate Framework Config

**If {detected_stack} is `frontend` or `fullstack`:**

Create `playwright.config.ts` or `cypress.config.ts` with:

- **Timeouts**: action 15s, navigation 30s, test 60s
- **Base URL**: env fallback (`BASE_URL`)
- **Artifacts**: retain-on-failure (trace/screenshot/video)
- **Reporters**: HTML + JUnit + console
- **Parallelism**: enabled (CI tuned)

Use TypeScript if `use_typescript: true`.

**If {detected_stack} is `backend` or `fullstack`:**

Create the idiomatic test config for the detected framework:

- **pytest**: `pyproject.toml` `[tool.pytest.ini_options]` or `pytest.ini` with markers, test paths, coverage settings
- **JUnit**: `build.gradle`/`pom.xml` test configuration with JUnit 5 dependencies, Surefire/Failsafe plugins
- **Go test**: no config file needed (Go convention); optionally create `Makefile` test targets
- **xUnit**: `.csproj` test project with xUnit and coverlet dependencies
- **RSpec**: `.rspec` config file with `spec_helper.rb` and `rails_helper.rb` (if Rails)

---

## 3. Environment Setup

Create `.env.example` with `TEST_ENV`, `BASE_URL`, `API_URL`.

**Stack-conditional environment files:**

**If {detected_stack} is `frontend` or `fullstack` (Node.js):**

- `.nvmrc` using current LTS Node (prefer Node 24+)

**If {detected_stack} is `backend`:**

Create the idiomatic version file for the detected language:

- **Python**: `.python-version` with current stable Python (prefer 3.12+)
- **Java**: `.java-version` or `JAVA_HOME` documentation in `.env.example`
- **Go**: Go version is already in `go.mod` (no additional file needed)
- **C#/.NET**: `global.json` with SDK version if not already present
- **Ruby**: `.ruby-version` with current stable Ruby

---

## 4. Fixtures & Factories

Read `{config_source}` and use `{knowledgeIndex}` to load fragments based on `config.tea_use_playwright_utils`:

**If Playwright Utils enabled:**

- `overview.md`, `fixtures-composition.md`, `auth-session.md`, `api-request.md`, `burn-in.md`, `network-error-monitor.md`, `data-factories.md`
- Recommend installing `@seontechnologies/playwright-utils`

**If disabled:**

- `fixture-architecture.md`, `data-factories.md`, `network-first.md`, `playwright-config.md`, `test-quality.md`

**If Pact.js Utils enabled** (`config.tea_use_pactjs_utils`):

- `pact-consumer-framework-setup.md` (CRITICAL: load this for directory structure, scripts, CI workflow, and PactV4 patterns)
- `pactjs-utils-overview.md`, `pactjs-utils-consumer-helpers.md`, `pactjs-utils-provider-verifier.md`, `pactjs-utils-request-filter.md`, `contract-testing.md`
- Recommend installing `@seontechnologies/pactjs-utils` and `@pact-foundation/pact`

**If Pact.js Utils disabled but contract testing relevant:**

- `contract-testing.md`

**If Pact MCP enabled** (`config.tea_pact_mcp` is `"mcp"`):

- `pact-mcp.md`

Implement:

- Fixture index with `mergeTests`
- Auto-cleanup hooks
- Faker-based data factories with overrides

---

## 5. Sample Tests & Helpers

**If {detected_stack} is `frontend` or `fullstack`:**

Create example tests in `{test_dir}/e2e/` demonstrating:

- Given/When/Then format
- data-testid selector strategy
- Factory usage
- Network interception pattern (if applicable)

**If {detected_stack} is `backend` or `fullstack`:**

Create example tests in the idiomatic location for the detected language:

- **Python**: `tests/test_example.py` with pytest fixtures, parametrize, and factory usage
- **Java**: `src/test/java/.../ExampleTest.java` with JUnit 5 annotations, `@BeforeEach` setup
- **Go**: `example_test.go` alongside source with table-driven tests and `testify` assertions
- **C#/.NET**: `tests/ExampleTests.cs` with xUnit `[Fact]`/`[Theory]` and fixture injection
- **Ruby**: `spec/example_spec.rb` with RSpec `describe`/`context`/`it` and factory_bot

Create helpers for:

- API clients (if needed)
- Network utilities (frontend/fullstack only)
- Auth helpers
- Test data factories (language-idiomatic patterns)

**If `config.tea_use_pactjs_utils` is enabled and runtime is Node.js/TypeScript** (i.e., `{detected_stack}` is `frontend` or `fullstack`, or `{detected_stack}` is `backend` with Node.js/TypeScript runtime):

Create Node.js/TypeScript contract test samples per `pact-consumer-framework-setup.md`:

- **Consumer test**: Example using PactV4 `addInteraction()` builder + `createProviderState` + real consumer code with URL injection (`.pacttest.ts` extension)
- **Support files**: Pact config factory (`pact-config.ts`), provider state factories (`provider-states.ts`), local consumer-helpers shim (`consumer-helpers.ts`)
- **Vitest config**: Minimal `vitest.config.pact.ts` (do NOT copy settings from unit config)
- **Shell scripts**: `env-setup.sh`, `publish-pact.sh`, `can-i-deploy.sh`, `record-deployment.sh` in `scripts/`
- **CI workflow**: `contract-test-consumer.yml` with detect-breaking-change action
- **package.json scripts**: `test:pact:consumer`, `publish:pact`, `can:i:deploy:consumer`, `record:consumer:deployment`
- **.gitignore**: Add `/pacts/` and `pact-logs/`

### 6. Orchestration Notes for This Step

For this step, treat these work units as parallelizable when `resolvedMode` is `agent-team` or `subagent`:

- Worker A: directory + framework config + env setup (sections 1-3)
- Worker B: fixtures + factories (section 4)
- Worker C: sample tests + helpers (section 5)

In parallel-capable modes, runtime decides worker scheduling and concurrency.

If `resolvedMode` is `sequential`, execute sections 1→5 in order.

Regardless of mode, outputs must be identical in structure and quality.

### 7. Save Progress

**Save this step's accumulated work to `{outputFile}`.**

- **If `{outputFile}` does not exist** (first save), create it with YAML frontmatter:

  ```yaml
  ---
  stepsCompleted: ['step-03-scaffold-framework']
  lastStep: 'step-03-scaffold-framework'
  lastSaved: '{date}'
  ---
  ```

  Then write this step's output below the frontmatter.

- **If `{outputFile}` already exists**, update:
  - Add `'step-03-scaffold-framework'` to `stepsCompleted` array (only if not already present)
  - Set `lastStep: 'step-03-scaffold-framework'`
  - Set `lastSaved: '{date}'`
  - Append this step's output to the appropriate section of the document.

Load next step: `{nextStepFile}`

## 🚨 SYSTEM SUCCESS/FAILURE METRICS:

### ✅ SUCCESS:

- Step completed in full with required outputs

### ❌ SYSTEM FAILURE:

- Skipped sequence steps or missing outputs
  **Master Rule:** Skipping steps is FORBIDDEN.
